Aurum Gold
Analysis Laboratory
We employ clinical-grade X-Ray Fluorescence (XRF) scanners and traditional chemical Fire Assay (cupellation) to certify your gold assets with absolute molecular precision at Authentic Gem Lab.
Scientific Assaying Methods
A comprehensive three-stage testing system guarantees that every specimen is mapped inside and out.
XRF Spectrometry
Non-destructive optical scanning that exposes the elemental components (Gold, Silver, Platinum, Palladium, Nickel, Zinc) on the surface of your metal with 0.01% accuracy.
Chemical Fire Assay
The traditional gold standard of purification. A tiny scraping is combined with lead and cupelled at 1050°C, separating pure gold from all base metals to verify Karatage.
Ultrasonic Core Scans
Advanced sound wave penetration scans the internal density of bullion bars, immediately exposing tungsten core insertions or heavy-metal plating without cutting the bar.
Gold Karat Purity Standards
